One is a mountain electronics 10mm FET I never got around to using. One is some performer made by a blf member I cant remember. The driver was a big deal at the time I purchased it so maybe chops can post a picture of it and someone will recognize it. The package it came in came from Croatia.
Yep that is it. Looks like I have an old version but it should be a 12 amp capable driver. For sale : LD-2 and LD-M2 driver (Updated) All my comments when ordering are here.
It runs on a single AA and has a small 3mm led that lights via a momentary switch on the back, to check the time at night.
It is pretty bright, my planned mod was to add a high value resistor in series with the led and replace the momentary switch with a slide-switch, so the clock can be lighted all night at a non-disturbing brightness. I like that much better.
I was surprised to like the tint of the led, pretty good for a cheap travel clock, so before starting the mod I checked the tint with the spectrometer.
And good it was indeed: 2300K, 96.3CRI, R9=83, duv –0.022. This is a holy grail led , where did the Hema source it?
I would love to see some new leds with round die. But for now i am really happy to have my SBT-70 Aspheric on my shelf. Again thanks to DB Custom for making it possible.
Had to mill the underside of the led cover thinner to make space for the SBT-70. The cover barely touches the glass above the led. Took some time to center it but i think now it looks good.
Before the assembly every part was really good cleand and i still have a few dust spots under the lens .
I would love to add some shots from this led in moon mode. The blue shining line arround the led looks so cool. But with my phone it is not visible. Maybe i can find someone in my area to take a few nice shots.
I fixed my old bluetooth speaker…the stupid microUSB charge port broke off the mother board….so I opened it…soldered in a tp4056 module, cut end off bad USB cable and wired in…closed it up…yay…can charge the battery and listen to my audiobooks on my drive to work
I’m at the proof of concept stage, testing layout.
I’m building a:
Replica prop from Pulp Fiction
Bonfire/Fireplace emulator
Suitcase with ~18000mAh capacity + 5V USB output
Very big over-engineered ambient temperature measurement device
Orange quad mule with unnecessary active cooling, just because!
It’s gonna have 9 x 18650 LG S3 2000mAh cells loaded when it’s done.
It has a 3A charge circuit, the 1A micro-usb took forever charging this many cells at once.
I’m still considering adding a second emitter choice, so it can shift from orange to perhaps a warm white.
It’s running on a Emisar D4 driver, flashed with the latest Anduril 2019-06-02 firmware. So it has all the blinkies.
The 4 leds are salvaged from a Orange Beacon light. All I can find is that they are “3W”. Have 4x XP-E2 P3 amber LEDs on order, for MOAR OUTPUT!
Still need to find something to cover the leds, to act as a diffuser. Something that can fold, or fit in the case when closed.
